Description

With the aid of Computed Tomography (CT), physicians can reconstruct cross sections of a patient's body and learn in-depth details about the shape and anatomy of their organs, as well as, to some degree, their functionality. Starting with the idea of tomography and the basics of image reconstruction from projections, this chapter will concentrate on the fundamental concepts and technical development of CT. The advancements that led to the current design of multislice CT and cone-beam CT scanners are shown, along with the most crucial dose reduction strategies and a brief overview of typical picture artefacts and potential methods for their correction. Computed Tomography (CT) is a medical imaging technique that uses Xrays to create detailed cross-sectional images of the body. It is a valuable tool for diagnosing a wide range of medical conditions and injuries, including tumors, fractures, and internal bleeding.

The CT scanner consists of a rotating X-ray tube and a detector array that captures the X-rays as they pass through the body. The data collected by the detector is then processed by a computer to create the images. One of the main advantages of CT is its ability to produce images with high spatial resolution. This allows clinicians to visualize structures within the body with greater clarity and detail than other imaging techniques, such as traditional X-rays or ultrasound. CT can be used to image virtually any part of the body, including the head, chest, abdomen, and extremities. It is particularly useful for imaging complex structures, such as the brain and the chest, where traditional X-rays may not provide sufficient detail. In addition to its diagnostic capabilities, CT can also be used for image-guided procedures, such as biopsies and drainage procedures. In these cases, the CT scanner is used to guide the placement of a needle or catheter to a specific location within the body. There are several different types of CT scanners available, including singleslice, multi-slice, and cone-beam CT. Single-slice scanners use a single row of detectors to capture images, while multi-slice scanners use multiple rows of detectors to capture images in a shorter amount of time. Cone-beam CT is a specialized type of scanner used primarily for dental and orthopedic imaging. One of the most significant recent advancements in CT technology is the development of dual-energy CT. Dual-energy CT uses two different X-ray energy levels to differentiate between different types of tissues within the body. This can be particularly useful for imaging blood vessels, as it allows clinicians to distinguish between contrast material and calcified plaques. Another area of active research in CT is the development of spectral imaging techniques. Spectral CT uses a combination of different X-ray energies and detector materials to generate images with greater contrast and specificity than traditional CT. Despite its many benefits, CT does have some limitations and risks. CT uses ionizing radiation, which can increase the risk of cancer over time. However, the amount of radiation used in CT is generally considered to be safe, and the benefits of the diagnostic information obtained from a CT scan typically outweigh the risks.

Another potential risk of CT is contrast material reactions. Contrast material is a substance that is injected into the body to enhance the visibility of certain structures during imaging. While contrast material is generally safe, some people may experience allergic reactions or other adverse effects. Overall, CT is a valuable tool for diagnosing and treating a wide range of medical conditions. Its ability to produce high-quality images with high spatial resolution has made it an indispensable tool for clinicians and ongoing research is likely to continue to improve its capabilities in the years to come.
